Abstract

SE DESCRIBE UN METODO PARA PRODUCIR UNA LAMINA O PELICULA (3) DE RESINA TERMOPLASTICA, EN DONDE UN MATERIAL DE RESINA EN BRUTO AL CUAL HAN SIDO AÑADIDOS UNO O MAS ADITIVOS SELECCIONADOS DEL GRUPO COMPUESTO DE UN AGENTE DE NUCLEACION, POLVO FINO DE UN POLIMERO DE ELEVADO PUNTO DE FUSION, UNA RESINA DE PETROLEO, UNA RESINA DE TERPENO Y UN PEROXIDO ORGANICO SE MEZCLAN BAJO CALOR PARA FORMAR UNA LAMINA O PELICULA DE RESINA, LA LAMINA O PELICULA DE RESINA RESULTANTE SE PONE EN CONTACTO CON, Y ADHERIDA A LA SUPERFICIE EXTERIOR DE UN RODILLO (4) DE ENFRIAMIENTO QUE TIENE UNA SUPERFICIE TERMINADA EN ESPEJO O LA SUPERFICIE EXTERIOR DE UNA CADENA METALICA SIN FIN (5) QUE TIENE UNA SUPERFICIE TERMINADA EN ESPEJO, Y ENTONCES SE MUEVE A LO LARGO CON EL RODILLO O LA CADENA, Y DESPUES DE ESTO SE INSERTA, PRESIONADA Y ENFRIADA ENTRE LA SUPERFICIE EXTERIOR DE DICHO RODILLO DE ENFRIAMIENTO Y LA SUPERFICIE EXTERIOR DE DICHA CORREA METALICA SIN FIN. TAMBIEN SE DESCRIBE UN METODO PARA PRODUCIR UNA LAMINA O PELICULA DE RESINA TERMOPLASTICA, EN DONDE UN MATERIAL DE RESINA EN BRUTO A LA CUAL SE HA AÑADIDO UNO O MAS ADITIVOS SELECCIONADOS DEL GRUPO COMPUESTO DE UN AGENTE DE NUCLEACION, POLVO FINO DE UN POLIMERO DE ELEVADO PUNTO DE FUSION, UNA RESINA DE PETROLEO, UNA RESINA DE TERPENO, UN PEROXIDO ORGANICO Y UN COPOLIMERO POLIPROPILENICO CRISTALINO SE MEZCLAN BAJO CALOR PARA FORMAR UNA LAMINA O PELICULA DE RESINA, LA LAMINA O PELICULA DE RESINA RESULTANTE SE INSERTA ENTRE UN RODILLO (34) DE REFRIGERACION QUE TIENE UNA SUPERFICIE TERMINADA EN ESPEJO Y UNA CADENA (35) METALICA SIN FIN QUE TIENE UNA SUPERFICIE TERMINADA EN ESPEJO, ENTONCES ELLA ES MOVIDA Y ENFRIADA MIENTRAS QUE ES MANTENIDA EN CONTACTO CON LA SUPERFICIE EXTERIOR DE DICHO RODILLO DE ENFRIAMIENTO ENTRE DICHO RODILLO Y DICHA CADENA METALICA SIN FIN, Y DESPUES DE ESTO ES PRESIONADA DESDE EL INTERIOR DE DICHA CADENA METALICA SIN FIN, ENTONCES ES LIBERADA DEL CONTACTO CON DICHO RODILLO DE ENFRIAMIENTO Y ES ADICIONALMENTE MOVIDA MIENTRAS QUE SEMANTIENE ADHERIDA A DICHA CADENA METALICA SIN FIN Y ENTONCES DESPEGADA DE LA CADENA. LA LAMINA O PELICULA NO ORIENTADA ASI PRODUCIDA, QUE TIENE UNA SUPERFICIE DE GRAN BRILLO, UNA SUPERFICIE DE GRAN SUAVIDAD Y UNA GRAN TRANSPARENCIA, ES ADECUADA PARA ENVOLVER ALIMENTOS, MEDICINAS,ETC.A METHOD FOR PRODUCING A THERMOPLASTIC RESIN SHEET OR FILM (3) IS DESCRIBED, IN WHICH A RAW RESIN MATERIAL TO WHICH ONE OR MORE SELECTED ADDITIVES HAVE BEEN ADDED FROM THE GROUP COMPOSED OF A NUCLEATION AGENT, DUST POWDER HIGH MELTING POINT, AN OIL RESIN, A TERPEN RESIN AND AN ORGANIC PEROXIDE ARE MIXED UNDER HEAT TO FORM A RESIN FILM OR FILM, THE RESULTING FILM OR FILM IS CONTACTED WITH, AND ADHERED TO THE EXCESSIVE OF A COOLING ROLLER (4) THAT HAS A MIRROR-ENDED SURFACE OR THE OUTSIDE SURFACE OF AN ENDLESS METALLIC CHAIN (5) THAT HAS A MIRROR-ENDED SURFACE, AND THEN MOVES ALONG WITH THE ROLLER OR CHAIN, AND AFTER THIS IT IS INSERTED, PRESSED AND COOLED BETWEEN THE EXTERNAL SURFACE OF SUCH COOLING ROLLER AND THE EXTERNAL SURFACE OF SUCH AN ENDLESS METALLIC BELT. ALSO DESCRIBES A METHOD FOR PRODUCING A THERMOPLASTIC RESIN SHEET OR FILM, WHERE A RAW RESIN MATERIAL TO WHICH ONE OR MORE SELECTED ADDITIVES HAS BEEN ADDED FROM THE GROUP COMPOSED OF A NUCLEATION AGENT, DUST POWDER MELTING POINT, AN OIL RESIN, A TERPEN RESIN, AN ORGANIC PEROXIDE AND A CRYSTALLINE POLYPROPYLENE COPOLYMER ARE MIXED UNDER HEAT TO FORM A RESIN FILM OR RESIN FILM (A RESIN RESERTAIN IS INSERATED) COOLING UNIT THAT HAS A MIRROR-FINISHED SURFACE AND AN ENDLESS METALLIC CHAIN (35) THAT HAS A MIRROR-FINISHED SURFACE, THEN SHE IS MOVED AND COOLED WHILE IT IS KEPT IN CONTACT WITH THE EXTERNAL SURFACE OF SUCH COOLING ROLLER ON AND SUCH AN ENDLESS METALLIC CHAIN, AND AFTER THIS IS PRESSED FROM INSIDE THIS ENDLESS METALLIC CHAIN, THEN IS RELEASED FROM CONTACT WITH SUCH COOLING ROLLER AND IS ADDITIONALLY MOVED WHILE STILL HOLDING TO SUCH ENDLESS METALLIC CHAIN AND THEN TAKEN FROM THE CHAIN. THE LEAF OR FILM NOT ORIENTED SO PRODUCED, WHICH HAS A SURFACE OF GREAT BRIGHTNESS, A SURFACE OF GREAT SOFTNESS AND A GREAT TRANSPARENCY, IS SUITABLE FOR WRAPPING FOODS, MEDICINES, ETC.
